Ivermectin can be used topically to kill mange mites and may also kill lice and fur mites. It is safe for pregnant sows and young that have reached 12 ounces (340 grams) in weight. Repeat treatment at least once 7 to 10 days later to kill emerging mites (eggs are not killed). Treat all guinea pigs simultaneously. For more information and cautions, read www.guinealynx.info/ivermectin.html. Remember, the safest way to treat your guinea pigs for mites is to see a vet.

Purchase a bottle of Ivomec Pour-On 0.5% solution or a generic 0.5% solution (see: www.guinealynx.info/ivermectin_products.html). Each ml (cc) contains 5 mg ivermectin (5 mg/ml). Guinea pigs are dosed at 0.5mg/kg. This amount of ivermectin is found in 0.1 cc of this solution. Measure carefully to avoid a deadly overdose.

To properly treat your pets at the recommended rate of 0.5mg/kg, you must have an accurate weight for each animal. Multiply their weight in kilos by 0.1cc (the dose for a 1 kilo pig) to determine the dose in cc's. The following table may help you determine the proper dose in cc's:

Use a 1 cc syringe to draw the dose and apply it to the skin behind each ear. Part of the dose can also be applied directly to areas of hair loss and/or the skin on the rump. Fold over some fur and rub it in. Avoid contacting the ivermectin directly with your finger so the animal receives the entire dose (this product is also a human medication). The entire dose will look like two or three drops.
DO NOT DRAW MULTIPLE DOSES TO TREAT SEVERAL GUINEA PIGS AT ONE TIME.

If the entire dose does NOT look like it is approximately two or three drops, DO NOT TREAT YOUR GUINEA PIG YOURSELF! Repeat at least once, 7 to 10 days later. Store ivermectin at room temperature away from light.
